Figure 3: Values of total testosterone and androstenedione in obese and non obese patients with polycystic ovary syndrome and in control women. Box-and-whiskers plots of basal levels of androgens. The line within each box represents the median. Upper and lower boundaries of each box indicate 75th and 25th percentiles, respectively. The whiskers (above and below) show the upper and lower adjacent values, respectively. The levels of testosterone are significantly greater in the obese patients with PCOS compared with non obese PCOS patients and controls. Also, the testosterone levels are significantly greater in non obese PCOS patients than in control women. There are no significant differences in the levels of androstenedione.
